CONCRETE RAILWAY-'TIE- SPECIFIGATION forming part of Letters Patent No.759,852, dated May 1'?, 1904:.

Application filed June 8, 1903. Serial No. 160,452. (No model) To allwhom it may concern:

Be it known that we, LOUIS BEEZER and MICHAEL J. BEEZER, citizens of theUnited States, residing at Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented or discovered new and usefulImprovements in Concrete Railway-Ties, of which the lfollowing is aspecification.

In the accompanying drawings, which make ro part of this speciication,Figure 1 is a plan of a tie constructed in accordance with ourinvention,the central portion being removed. Fig. 2 is a cross-section on the line2 2 of Fig. 1. Fig. 3 is a longitudinal section on the line f5 3 3 ofFig. l.

Our invention relates to railway appliances, and more particularly torailway-ties and rail- :t'astening devices.

It is the object of our invention to provide zo a substitute for thecommon wooden ties in use, which, owing to the scarcity of suitable woodand their increasing cost, must give way to a superior article,eifecting a great saving in maintenance. We have devised a tie which 2 5is thereby cheaper and one which will be practically indestructible. Ourtie being thoroughly waterproofed in all its parts will not be affectedby the Water or frost, and the parts are so strongly united that theywill not become broken or separated. We also give the rails a suitableelastic bed-cushion, preferably of compressed cork capped with a flangedsteel plate, which not only makes the train less noisy and lessinjurious to the rolling-stock,

3 5 but also prevents to a large degree the pounding action oi' thecar-wheels from being transmitted so suddenly to the concrete portion ofthe ties, the result being that the ties will not become cracked orbroken.

40 Referring to the drawings, A represents the tie as a whole', havingthe beveled sides and ends, as shown in Figs. 1 and 2, which retain thetie more securely to the ballast. Nearly l all the body of tie is madeot' slag cement, concrete, or other plastic material, which will set orbecome hard and has embedded in it when formed a plate B, preferably ofsteel, having the bottom and the upwardly-extending fianges b', whichare inclined toward each otherl and lie substantially parallel with thesides of the tie, the plate thus having a U-shape cross-section. Thesides and the bottom b are provided with numerous holes b2 punched,which allow the concrete to pass through, so as to tie or bind theconcrete into a more thoroughly solid homogeneous mass than would be thecase if the concrete were unconnected along the entire surface ofunperforated plate. The plate B extends almost the entire length of thetie. l 6o Seated under each rail and between the flanges o and on thebottom of the plate B is a composition block D, made, preferably, ofwood or compressed sawdust and glue, &c.

On top of block D and partially below the top of the concrete is a layerof compressed ground cork, wood-pulp, liber, or ordinary wood F, formingan elastic cushion, which makes the train less noisy and prevents to alarge degree injury to the rolling-stock and the pounding action oit'the wheels from being transmitted so suddenly and sharply to theconcrete portion of the tie.

A pressed-steel cap-plate G is seated on the cushion F and has its edgesg flanged or turned 7 5 down, so as to stifen the same and cover andprotect the upper edges of the cushion, keeping out water and preventingthe ultimate squeezing out of the cork.

The rail E lies directly on the plate G and 8o is held in place by theclips I-I and the lagbolts I-I, screwed down through the plate Gr, the'cork g, and the block D. The block is provided with the tapered holesI, (shown in dotted lines,) which holes are smaller than the 8 5diameter ot' the lag-bolts and do not extend so far into the block D asthe lag-bolts are intended to go. The large tapering lagbolts arescrewed into the holes I, which are hereby widened and lengthened, asshown on Figs. 2 90 and 3.

Lying on top of plates G ahd the flanges of the rail E are the clips H',strung on the lag'- bolts, as shown. The under side oi' each clip, onthe portion thereotl nearest the rail-fiangc, is beveled upwardlyslightly, so that it will not engage that part of the plate G betweenthe rail-Hanges and the outer sides of the bolts before it engages thetop of the said lianges. The beveling of the clips insures that theywill 10o have one end on a rail-ange, with no obstruction in the way ofapplying or tightening their clamping action. The heads H2 of thelag-bolts are screwed down tight on the clips, so as to hold the railsecurely in place on the tie.

The composition block D is very strong and is waterproof, and it is,furthermore, protected from water by the cork layer F and the angedcap-plate G, also by the overhanging flanges b* of the concrete, beinglocked securely by the slag-concrete walls surrounding the same.

The concrete we prefer to use is made of slag' and cement. We do notdesire to be limited to this composition, as other plastic hardeningcompositions may be used to accomplish the same result. f

Having described our invention, we claim-4 between'side plates, elasticmaterial 'on said vday of June, 1903.
